Four variables in effect here...BOAT wrote:Matt, if the hull speed is 7 knots why can't I hold that speed in a 12 knot wind? I can get there real fast but every 10 or 20 seconds it drops down to 6-1/2 and then shoots back up to 7 for a little bit and then just drops back down to 6-1/2.
The consistency of the wind acting on the sails.
The efficiency of the sails / sail trim.
The efficiency of the hull, dagger board, rudders in the water and their trim / drag.
The state of the water - flat, waves, etc.
All inconsistent variables.
